overheating wj

I am still having overheating issues.

So far I have changed the thermostat,changed fluid 50/50 mix,fan is running and turns on at @210degrees but doesn't keep it cool. Gets up to @ 230+ then I shut it off don't want to overdo it.

What is the next step?? Water pump,radiator,bigger better( more c f m 's from fan)

Wife said I can't do any other mod's till it runs good. It killing me...... I want to lift and get a/t tires so I can off road.

Check again. It's either a 4.0 straight 6 or a 4.7 V8.

Overheating WJ

I had a similar problem. I found out that my electric fan motor was wearing out and only running at half speed. Changed the fan motor and everything was fine.
